Data Safety and Security

I am hesitant to provide my email address. How will it be used?
We guarantee that your email address will NEVER be sold, rented or provided to any third party. Users will be emailed only for service-related purposes (notifying you that your file is ready for download or that your file has been transferred) and nothing more. No other emails will be sent. Check our TOS and Privacy Policy for more information.

What happens with my uploaded documents?
All uploaded documents are accessible only for service-related purposes and visible only via a URL sent to users via email or through our online interface. Documents that are not stored are deleted from our servers permanently after their URLs expire. The visibility of stored documents is completely under the control of the user, meaning that the user decides whether he or she wants to make the document publically available, share it with certain individuals or keep it completely private.

The second component of cometdocs that is licensed is the document preview using Flexpaper from Devaldi in Australia. This allows our users to view their documents right from within their browser window.
